How did you calculate the RPM drop with the other final drive? Gear spacing shouldn't change with a shorter or taller final drive, just the speed you're going for any given RPM would change.

I made a quick spreadsheet which matches yours with the stock FD, but if I change the FD it doesn't change the RPM drop to the next gear, just the output RPM at the wheel (I didn't calculate speed, just wheel RPM).
